The positive outcome of a comprehensive orthodontic treatment is highly dependent on the communication between orthodontists, oral surgeons and patients. Purpose of this study was to detect with the help of a questionnaire if laypeople differ significantly from dental students, orthodontists and oral surgeons int the evaluation of facial profiles and the neccessitiy with regards to their need of treatment. A profile picture serie of a female and male model were used for the questionnaire. Both models were of Caucasian descent. There had been 10 profile pictures of the female and male model to be judged. In total 9 pictures of each photo model showed a changed profile situation in the vertical and saggital plane. The 10th picture of each model was a randomly chosen copy of one of the nine foregone pictures. The voters had to judge the 10 pictures by reference to their aesthetics and need of treatment with the help of a "10-point numerical rating scale". 5 participants of each group have filled out the test again after one week. The orthodontists and oral surgeons judged in general the profile pictures more critical than the laypersons. Furthermore the orthodontists and oral surgeons would advise more often than the laypersons a treatment for unattractive facial profiles. The study also indicates a development, which reveals that voters with a more sophisticated education in dental sections, compared to laypeople judge facial attractiveness more crtiticaly.
